"KEY*"我收到一个 500k+ 行的大文件，但所有内容都在 A 列中。我需要运行一个宏，将数据转换为矩阵形式，但只有在 ActiveCell 中找到时才会创建一个新行。例如：

| KEY 4759839 | asljhk | 35049 | | sklahksdjf|
| KEY 359     | skj    | 487   |y| 2985789   |

我文件中的上述数据最初在 A 列中如下所示：

KEY 4759839
asljhk
35049

sklahksdjf
KEY 359
skj
487
y
2985789

注意事项：

  • 空白单元格也需要转置，所以宏不能基于emptyCell停止
  • KEY 之间的单元格数量不是恒定的，因此它实际上需要读取单元格以知道它是否应该创建一个新行
  • 它可以根据一行中的 20 个空单元格停止，也可以提示输入最大行数
  • （可选）如果一行中的最后一个项目有某种视觉指示器会很好，这样就可以判断最后一个项目是否为空白单元格

我四处搜索，发现一个宏具有相同的一般主题，但它基于每 6 行，我没有足够的知识来尝试修改它以适应我的情况。但如果它在这里有帮助，那就是：

Sub kTest()
    Dim a, w(), i As Long, j As Long, c As Integer
    a = Range([a1], [a500000].End(xlUp))
    ReDim w(1 To UBound(a, 1), 1 To 6)
    j = 1
    For i = 1 To UBound(a, 1)
        c = 1 + (i - 1) Mod 6: w(j, c) = a(i, 1)
        If c = 6 Then j = j + 1
    Next i
    [c1].Resize(j, 6) = w
End Sub

我将不胜感激您能给我的任何帮助！

这适用于您在问题中提供的示例数据 - 它在从 B1 开始的表中输出结果。它在我的机器上运行 500k 行不到一秒。

Sub kTest()
    Dim originalData As Variant
    Dim result As Variant
    Dim i As Long
    Dim j As Long
    Dim k As Long
    Dim countKeys As Long
    Dim countColumns As Long
    Dim maxColumns As Long

    originalData = Range([a1], [a500000].End(xlUp))

    countKeys = 0
    maxColumns = 0

    'Calculate the number of lines and columns that will be required
    For i = LBound(originalData, 1) To UBound(originalData, 1)
        If Left(originalData(i, 1), 3) = "KEY" Then
            countKeys = countKeys + 1
            maxColumns = IIf(countColumns > maxColumns, countColumns, maxColumns)
            countColumns = 1
        Else
            countColumns = countColumns + 1
        End If
    Next i

    'Create the resulting array
    ReDim result(1 To countKeys, 1 To maxColumns) As Variant

    j = 0
    k = 1
    For i = LBound(originalData, 1) To UBound(originalData, 1)
        If Left(originalData(i, 1), 3) = "KEY" Then
            j = j + 1
            k = 1
        Else
            k = k + 1
        End If
        result(j, k) = originalData(i, 1)
    Next i

    With ActiveSheet
        .Cells(1, 2).Resize(UBound(result, 1), UBound(result, 2)) = result
    End With

End Sub

测试和工作： 

    Sub test()
    Row = 0
    col = 1

    'Find the last not empty cell by selecting the bottom cell and moving up
    Max = Range("A650000").End(xlUp).Row 'Or whatever the last allowed row number is

    'loop through the data
    For i = 1 To Max
        'Check if the left 3 characters of the cell are "KEY" and start a new row if they are
        If (Left(Range("A" & i).Value, 3) = "KEY") Then
             Row = Row + 1
             col = 1
        End If

        Cells(Row, col).Value = Range("A" & i).Value
        If (i > Row) Then
            Range("A" & i).Value = ""
        End If
        col = col + 1

    Next i
End Sub
